However, insects do not breathe through their mouths, nor do they have lungs. In fact, insects are equipped with tracheal tubes terminating in pores, called spiracles, running along their abdomens. Insect trachea, much like the structure inside a lung, branch off into smaller and smaller trachea, but end deep in the various tissues of the insect; here, oxygen and carbon dioxide are exchanged continually. Due in part to the largely-passive gas exchange, insects are unable to 'breathe' very fast. This limitation is probably one reason why insects remain relatively small. It is possible to protect some plants from pests by spraying them lightly with castor oil (for example) as the oil effectively blocks their spiracles, suffocating them.
All insects breathe through their skin.
Maggots breathe oxygen. They are insect larvae and are similar in this regard to all other insects.
Insects use spiracles as openings in their exoskeleton to allow air to enter and exit their bodies for respiration. This is where oxygen is taken in and carbon dioxide is released during the breathing process.
The way in which insects and fish breathe differs in the process in which each receives oxygen. Insects use a tracheal system to receive oxygen and fish use their gills to filter oxygen out of the water.
They have gills that allow them to derive oxygen from the water, and also absorb water, therefor receiving more oxygen. While the above answer applies to mayfly nymphs which live under water it doesn't apply to adult mayflies which, like their name says, fly. Adult mayflys breathe in the same way as all insects, via tiny openings in their exoskeleton.
All insects breathe through their skin.
Insects breathe by tracheal structure. The reason insects breathe with their trachea is because they do not have lungs.
